Looks like they are adding per-state maps on the ECMWF weather.us site. Maps are pulling up blank but I'm assuming that's because they are in the process still as these weren't available earlier this morning.

Very likely snow in the air at some point. Watching for an inch or 2 Friday or Sunday mornings if we have any type of steady precip around. Sunday morning looks really nice with the outflow setting up and precip moving up from the SW, but that is a long ways away in model land.

Sitting at 58 right now. Most trees around where I work in Bothell are already bare.

It will be a perfect evening.

Those must be a specific type of non-native tree... most of the trees in the Seattle area and out here still have leaves and still showing great color. The drive from Bellevue to North Bend this afternoon was spectacular.

Trying to figure out how to shield the instrument from the sun so I don't get high readings in the afternoon when the sun is out, but still avoid covering any part of the solar panels.

That can be really difficult. I have never had good luck using shielding in direct sunlight. You might try using using two layers of shielding with a gap in between with fan aspiration to give good air flow. Keeping the outer layer very clean and as white as possible will help.

Successive model runs have pushed up the timing of this event. It's now looking colder but drier up here going into Friday morning. Temperatures should be decently cold for snow with 925mb temps approaching -3C ~ -4C but getting moisture at the same time may again be a problem.

Awesome, look forward to tracking your obs. If you have a fan aspirated system, the unit should be fine in the sun. Even without that, the cooling fins on the station are designed for maximum ventilation, so as long as your station isn't sitting over asphalt or anything else that will absorb/conduct heat to the atmosphere, you should be fine, I suspect.

Also, you'll need the station in the open if you have a tipping bucket rain gauge attached to the ISS unit.

Yeah I'm going to get the Storm portion of the unit so I can measure rainfall. Yeah it's sitting away from my rooftop and is over grass/dirt. I did put a reflective shield (plywood with aluminum tape on it) in order to block the sun from the lower part of the unit and it does seem to help. I'm closer to the surrounding stations during max heating.
